Abstract:
Digital document libraries are an almost perfect application arena
for unsupervised neural networks.
This because many of the operations computers have to perform on
text documents are classification tasks based on ``noisy'' input
patterns.
The ``noise'' arises because of the known inaccuracy of mapping
natural language to an indexing vocabulary representing the contents
of the documents.
A growing number of papers is dedicated to the usage of self-organizing
maps to organize the contents of such digital libraries.
These papers assume the central availability of the data;
an assumption that is questionable given the massive amount of
available information.
In this paper we describe an approach for organizing distributed
digital libraries based on a system of independent self-organizing
maps each of which representing just a portion of the complete
digital library.
Furthermore, we argue in favor of integrating these independent
maps in a hierarchical fashion, again by means of self-organizing maps.
The integration is based on the trained low level maps.
